Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdriver set, socket set).
Ensure the vehicle is parked on a flat surface with the ignition turned off and the parking brake engaged.

2. Inspect and Clean the Camera

Locate the rearview camera, typically mounted on the trunk lid.
Remove any debris or dirt obstructing the camera lens using a soft cloth.
If the camera is physically damaged, proceed to replace it.

3. Check Wiring Connections

Access the rearview camera wiring harness by removing any trim panels or covers.
Inspect the wiring for any signs of wear, fraying, or corrosion.
Reconnect any loose connectors securely and ensure the wiring is intact. If damaged, replace the wiring harness.

4. Test Camera Power Supply

Use a multimeter to check the voltage at the rearview camera connector.
The camera should receive approximately 12V. If not, trace the wiring back to the source and check for breaks or bad connections.

5. Software Reset

Navigate to the Tesla's settings menu and perform a soft reboot of the infotainment system.
To do this, press and hold both scroll wheels on the steering wheel until the screen turns off and then back on.

6. Replace Camera (if necessary)

If the camera is confirmed faulty, remove it from its mounting.
Install the new camera by reversing the removal steps and connecting the wiring securely.
